Re: Resize on dirty array?

[James Peverill <jamespev@net1plus.com>]

I'll try the force assemble but it sounds like I'm screwed.  It sounds 
like what happened was that two of my drives developed bad sectors in 
different places that weren't found until I accessed certain areas (in 
the case of the first failure) and did the drive rebuild (for the second 
failure).  In the future, is there a way to help prevent this?  Given 
that the bad sectors were likely on different parts of their respective 
drives, I should still have a complete copy of all the data right?  Is 
it possible to recover from a partial two-disk failure using all the disks?

It looks like I might as well cut my losses and buy new disks (I suspect 
the last two drives are near death given whats happened to their 
brethren).  If I go SATA am I better off getting 2 dual port cards or 1 
four port?

Thanks again.

James
